Yeah she's been spayed...in my family we spay and neuter all animals....Hell, they even tried to neuter me...but I made it away with just a slight nip....

thank you all for your advice. I have never heard of the dog whisperer or It's me or the dog. I will look into them both.

Certain things have changed, my sister and her long time boyfriend broke up...and she and Luna moved back home...and since then my sister has been regressing, spending less and less time with her dog...and more time out with friends.
